Slowey was the lone member of the team’s seven-person draft class to not survive the initial round of cuts. Last year, nine of the 49ers’ 10 draft picks remained on the roster after final cuts. The lone exception was USC wide receiver Ronald Johnson, a sixth-round pick. Slowey was among six of the NFL’s 253 draftees who came from a Division II school.

** As a rookie last year, Hastings was on the practice squad for the season’s first 15 games before making his NFL debut at St. Louis on Jan. 1. He suffered a leg injury early in training camp and did not play in the first three preseason games.

** Tyms (6-3, 210), who has played just three of organized football, was an intriguing prospect, but was likely deemed too raw. Several teams have called to express interest in Tyms, according to his agent. He had three catches for 32 yards in the preseason.

** Hampton and Fleming do not count against the 49ers’ active roster and they will not be eligible to practice until Oct. 16. The 49ers will then have a three-week window to decide whether to activate them, release them or place them on injured reserve.

** Each of the 12 players waived today can be signed to the practice squad Saturday. Teams will trim their rosters from 75 to 53 players Friday.
